Jon Hoffman

Jon Hoffman has over 25 years of experience in the field of information technology. Over these years, Jon has worked in the areas of system administration, network administration, network security, application development, and architecture. Currently, Jon works as a senior software engineer for Syn-Tech Systems. Jon has developed extensively for the iOS platform since 2008. This includes several apps that he has published in the App Store, apps that he has written for third parties, and numerous enterprise applications. He has also developed mobile applications for the Android and Windows platforms. What really drives Jon the challenges that the field of information technology provides and there is nothing more exhilarating to him than overcoming a challenge. Some of Jon's other interests are spending time with his family, robotic projects, and 3D printing. Jon also really enjoys Tae Kwon Do, where he and his oldest daughter Kailey earned their black belts together early in 2014, Kim (his wife) earned her black belt in December 2014, and his youngest daughter Kara is currently working towards her black belt.

Circuit diagrams

The following diagram shows the Fritzing diagram for this project:

The middle sensor, shown in the diagram, represents the crash sensor because there isn't a Fritzing part for a crash sensor. The switch in the diagram has the same pin layout as the crash sensor shown earlier in this chapter.

In the diagram, we can see that all of the ground pins on the sensors are connected to the ground rail of the breadboard and all of the VCC pins on the sensors are connected to the power rail on the breadboard.

The analog out on the EZ1 Ultrasonic sonar sensor is connected to the A1 analog pin on the Arduino, the crash sensor is connected to digital pin 3 and the infrared sensor is connected to digital pin 2. The crash sensor also has a 4.7K pull-up resistor. Now that we have the sensors connected to the Arduino, let's look at the code for this project.
